SIGNAL APPARATUS FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 483,585, dated October4, 1892. Application filed December 7, 1891- Serlal No, 414,212. (Nomodel.)

To all whom it may concern.-

Be it known that. I, ARVID J. SANDGREN, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in SignalApparatus for Bicycles, of which the following is a specification.

This invention relates to signal apparatus for bicycles, the objectbeing to furnish an apparatus in which the sign al-bell is operated fromthe brake-lever of the machine, thereby enabling the bicyclist to soundan alarm without using an additional handle or other specialbell-ringing device.

In the drawings accompanying and forming a part of this specification,Figure 1 is a front view of the upper part of a bicycle, showing thehandle-bars and brake-lever and comprising a signal apparatus embodyingmy present improvements. Fig. 2 is an enlarged view of the signalapparatus on the line a a, Fig. 1, as seen from the right hand of saidline. Fig. 3 is a view similar to Fig. 2, illustrating the operation ofthe improvement. Fig. 4. is a view similar to Fig. 2, illustrating amodification of the apparatus.

Similar characters designate like parts in all the figures.

In the drawings, the upper end or shaft B of the usual head of thebicycle is furnished with the usual oppositely-disposed handlebars C andD for controlling the forward wheel of the bicycle. The brake-lever E isshown pivotally supported or fulcrumed at 2 by a bolt or pin carried inthe ordinary manner by a suitable bracket or like part, as 3, fixed onone of the handle-bars, as will be understood from the drawings. Theworking end 4. of the brake-lever is connected by a pivot 5 to the upperend of the usual brakerod 6, which rod extends downward to and connectswith the usual spring retracted brake G in the ordinary manner. Saidbrake may be of any ordinary construction. As shown in the drawings, itis of the well'known spoon form and is supposed to be movable toward andfrom the bicycle-wheel )V in the ordinary manner.

The signal-bell F is supported in a position immediately over andforward of the handlebars where these join the shaft B, being carried bya suitable arm, as 7, which is attached to said shaft (or to thehandle-bars, if so preferred) by a suitable clamp, as 8, which, as shownin the figures, is held in place by suitable clamp screws 9. Theposition of the bell is such that a short space exists between the loweredge of the bell and the working end 4 of the brake-lever when thislever is in its uppermost position. (Shown in Fig. 3.) The bell-strikeror tongue 10, as shown in Figs. 2 and 3, is carried by a spring-arm 12,which is fixed to the bell-supporting arm or standard 7 by means of ascrew or pin or like fastening at 13. The bell-striker normally standsfree of the bell, as shown in Fig. 2, and saidworking end l of thebrake-lever (when the brake is not in use) normally stands in engagementwith the bell-striker arm 12, as shown in Fig. 3. If now the handle end14 of the brake-lever F. be drawn slightly toward the handlebar D, theworking end of said lever will be thrown slightly below and away fromthe bell-striker arm, as shown by dotted lines at t in Fig. 2, so thaton suddenly releasing said lever it will be forcibly thrown by the usualleverretracting spring (not shown) upward against said striker arm,thereby throwing the striker by a sudden movement against the bell, asshown in Fig. 3, and making the required signal. By this means thebicycle-rider is enabled by only a slight movement of the brake-lever tostrike the signal-bell, as occasion may require, without releasing hishold of the handle-bar or having to use any additional or specialsignal-actuating device. hen the brake is to be used, the brake-lever isgiven a longer stroke, carrying the end at thereof entirely away fromthe bell-striker, as shown by solid lines in Figs. 2 and a.

The proper adjustment of the bell-striker relatively to the brake-leveris, in the form of apparatus shown in Figs. 1, 2, and 3, readilyeffected by sliding the clamp 8 up or down, as the case may require, onthe shaft B of the bicycle-head to secure the required co-action betweenthe brake-lever and said striker. By this means the signal apparatus maybe set to give the desired quality or quantity of sound by regulatingthe force of the striker blow.

In the modification shown in Fig. 4. the bellfixed bell-supporting arm,

striker arm 20 is lever of a different order, being pivoted midway ofits length, at 21, to the bell-supporting arm 7, as will be understoodfrom the drawings. In this form of apparatus the striker is within thebell, while the brake-lever operates upon the lower end of itssupporting-arm. It will be evident, however, that the principle of theapparatus is substantially the same as in the preceding figures ofdrawings and that the mode of operation is not materially diiferent.

Having thus described my invention, I claim- 1. In a bicycle, thecombination, With the shaft carrying the handle-bars and with thebrake-lever of the bicycle, of thesignal-bell,

and a bell-striker intermediate to the brakelever and bell and actuatedby said lever to strike the bell, substantially as described.

2. In a bicycle, the combination, with the shaft carrying thehandle-bars and with the brake-lever of the bicycle, of the adjustablythe bell carried by said arm, and a bell-striker, substantiallyas described, intermediate to the brake-lever and bell, whereby theoperation of the bellstriker by the brake-lever may be regulated byadjusting the position of said arm, substantially as described.

3. In a bicycle, the combination, With the shaft carrying thehandle-bars and with the brake-lever of the bicycle, of a signal-belladjustably supported adjacent to the brake-lever, and the bell-strikercarried by a springarm rigidly fixed at the end thereof opposite to thestriker and having its middle portion in position to be struck by thebrake-lever on the retraction thereof, substantially as described.

4. In a bicycle, the combination, With the handle-bar and with thebicycle-wheel, of the brake movable toward" and from the wheel, thesignal device and its striker carried with the handle-bar, and a levercarried with the handle-bar and havingits handle endadjacent to thehandle of said bar and constructed and connected to actuate both thesignal-striker and the brake, substantially as described.
